Hyundai insists on fee of R926 prior to answering if problem under Warranty on my new car

DO NOT purchase a Hyundai i20!!! The quality of aftercare warranty service exceptionally pathetic and makes no sense at all. The stitching on the passenger seat of my 65 year old mums new Hyundai i20, which I must add is hardly used is coming out. The Hyundai was purchased in June 2021 and currently has a mileage under 12000kms. Thinking that its a new car, we contacted the warranty department at Hyundai The GLEN. We spoke to Sello, who stated that I need to pay R926 for the "TECHNICIANS TO DIAGNOSE THE PROBLEM". They are unable to advise me with the aid of pictures if the stiches fall under the warranty or not. I was told that I have to pay the R926 for them to diagnose whether its under warranty or not. So basically, once you purchase a Hyundai, you will not get any assistance with regards to your warranty unless you pay a rather exorbetant fee of R926 to determine if its under warranty or NOT!! Absolutely distasteful and pathetic service. Our first Hyundai purchase, will definitely not invest in Hyundai ever again. Furthemore, head office offered no response to my query.
